I have a 1999 Chevy Suburban with a 5.7 Vortec enigine and 151,000 miles on it. For about a week the truck would stumble at part throttle. Scan showed O2 sensor/ changed that and fuel filter. Check engine light scanned again and showed manufacturer ignition problem or misfire. Then after putting 25 gallons of gas in truck the engine shut off going down the road. Fuel gauge went to past the full mark pointing almost straight down. Checked fuel pump relay - was fine. Decided must be fuel pump - replaced fuel pump and connector. Reinstalled fuel tank, reconnected battery and still does not run. Please help!
